Nitroarenes are reductively cyclized with an array of tetraalkylammonium halides and trialkylarnmonium chlorides in the presence of a catalytic amount of a ruthenium catalyst along with tin(II) chloride dihydrate at 180° to afford the corresponding quinolines in moderate to good yields. The addition of tin(II) chloride dihydrate is necessary for the effective formation of quinolines and toluene is
The synthesis of quinoline derivatives by cyclocondensation of anilines with 1,2‐ethanediol, 1,2‐propanediol, and 1,2‐butanediol in the presence of iron‐containing catalysts was performed for the first time.

Substituted quinolines were synthesized by the reaction of aniline derivatives with aliphatic alcohols and CCl4 upon the action of the FeCl3·6H2O catalyst.
A variety of aminoarenes react with aliphaticaldehydes in the presence of a catalytic amount of a rhodium complex and an excess amount of the corresponding nitroarenes at 180 °C to give 2-alkyl- and 2,3-dialkyl-substituted quinolines in excellent yields. Among the rhodium complexes examined, [Rh(norbornadiene)Cl]2 exhibits the highest activity as a catalyst. Thus, 2-methyl-, 2-ethyl-3-methyl-, 2-propyl-3-ethyl-
在催化量的铑配合物和过量相应硝基芳烃的存在下,多种氨基芳烃在 180 °C 下与脂肪醛反应,以极好的收率得到 2-烷基和 2,3-二烷基取代的喹啉。在所检测的铑配合物中,[Rh(降冰片二烯)Cl]2 作为催化剂表现出最高的活性。因此,2-甲基-、2-乙基-3-甲基-、2-丙基-3-乙基-和2-丁基-3-丙基喹啉衍生物很容易从氨基芳烃和乙醛、丙醛、丁醛和戊醛中获得分别。

Anilines react with allylammonium chlorides in an aqueous medium (H2O–dioxane) in the presence of a catalytic amount of RuCl2(PPh3)3 together with SnCl2·2H2O to give the corresponding quinolines in moderate to good yields. The existence of SnCl2·2H2O is necessary for the effective formation of quinolines, and a reaction pathway involving amineexchange reaction between anilines and allylammonium chlorides
